Blizzard 1260 woes

[srg86]

Hi

I have a Blizzard 1260 with a 16MB single sided SIMM for my A1200 but most of the time I've had it I've had to go back to my 1230-IV because of GURUs

If I don't have any 040 or 060 libraries then the machine is rock solid stable, no crashes at all *not tried any software that uses the unused FPU instructions* but the trouble comes once I've installed the Phase 5 libraries off the disk or even after updating them to the later versions. I'm using what I downloaded from http://phase5.a1k.org/. After that, I get these troubles:

ShowConfig shows CPU as 68040/68882 not 68060 and then crashes with GURU 80000003

Wordworth 2AGA and Final Writer 5 both crash with GURU 8000000B

If I run Lha from C then after running most of things in C then cause GURUs 80000003, 80000004 or 8000000B especailly Mount and Assign so I have to replace them with what's on my Workbench disk.

I'm running Kickstart 39.106 and Workbench 39.29, my A1200 has motherboard revision 2B and I'm running from a 200W PC PSU

Is there anything that I have missed to get this machine stable?

Thanks :-)

Heys srg86, Welcome to the EAB

lets see...

now if you have done all this before (wich you might already done) please forgive me.

1. change memory
2. see if there are any differnece in DCE drivers and Phase 5
heres where http://amiga.resource.cx/exp/blizzard2060

3. try re-installing new 060libs etc.
4. run without memory
5. disable maprom


see how you get on with these srg86

best of luck m8.

Sell it... to me... cheap!!

I wonder if the memory is flakey? try diff SIMM ?

Right, interestinly if I run with no fast RAM all the crashes go away, but then it worked reliably with fast ram but no libraries. I have tried the SIMM in my 1230-IV and it seems to be fine.

I have tried it with a different SIMM but no difference

I have run both the DCE drivers and the Phase 5 ones come to think of it and there isn't any difference.

it happens with maprom on or off

could the cpu060 command help?

he he he well if its just these annoying libraries, I have other plans he he

ooh update!

I get the same Final writer GURU with my BlizzardPPC's 25MHz 68040.

Aha, a combination of motherboard 2B, gurus ending in 0003, 0004 and 000B, and an 060 accelerator can only mean one thing - your motherboard has the infamous bus timing fault problem. You either need to perform the bugfix as documented on the Aminet (or get someone to do it for you) or get hold of a motherboard that isn't revision 2B or 1D.4.

The fault only affects 1D.4 and 2B motherboards when used with 040 or 060 accelerators. Some are more susceptible than others. Removing the RAM and/or libraries will cause the card to slow down, probably just enough to avoid the majority of the crashes. You could try tweaking the CPU60 (or was it CPU060? The Apollo had one, and the Blizzard had the other) command's settings - I found that switching off things like the data cache and superscalar mode helped a little. The only real solution is the hardware fix.

Oh, ShowConfig will only ever say that you've got an 040 - it was written before the 060 was released, and so it has no knowledge of that CPU. It makes the best guess it can.

One other thing you can check - do you have the latest version of SetPatch installed (ie. the one that comes with the 060 libraries)? Should be in the C: directory, and it should be called near the start of your S:startup-sequence file.

Ah, and another thing you can check. An older version of the PowerPacker library hates the 060. Check that the files you're trying to run aren't compressed, and if they are, get the latest PowerPacker.library file from the Aminet.

But yeah, this sounds like the bus timing fault bug. I had identical problems for about 18 months when I had an Apollo 060 - couldn't work out what it was. I swapped the hard drive, re-installed Workbench, swapped the RAM, fiddled with the PSU, tinkered with the ROMs, ran the computer without the case on, ran it with fans attached, everything. It was only later when I discovered the hardware bugs and got a fixed motherboard from Eyetech (who no longer sell Amiga kit) that everything worked properly.

Except 3.9 at least BB2 should recognize 060 ok I think.

Thanks for the replys! Sorry that I haven't been able to get back to you quicker.

Right! Problem Solved!! It was a MaxTransfer Problem! I had forgotten to set the MaxTransfer on my workbench partition before installing workbench and only did it after installation, so I think a workbench file had become corrupted somwhere. I reinstalled workbench and the libraries and the machine and all my software are now rock solid stable on both my 040 and 060.

As for lha, I downloaded the latest version from aminet and am using that now and it doesn't cause any troubles.

Excellent srg86!!!!

glad you got it sorted!!
